摘要：The present research was conducted for the purpose to find out the effect of sowing dates and irrigation schedule influenced on yield and yield components of berseem in district Peshawar. The experiment was carried out at New Developmental Farm, The University of Agriculture Peshawar, Khyber Paktunkhwa, Pakistan during 2012-2013. The experiment was planted in randomized complete block design (RCBD) with three replication having split plot arrangements. Irrigation schedule (2, 5, 7 and 10) were allotted to main plots (Factor A) and Four sowing dates (15 th November 2012, 15 th December 2012, 15 th January 2013, and 15 th February 2013) were allotted to sub plots (Factor B). Plots sown in November and December showed better performance as compared with sowing in January and February. Sowing dates had significant effect on all parameter. Maximum receme weight (2.99 g), thousand grain weight (3.52 g), number of seeds head -1 (45), biological yield (8003 kg ha -1 ) and seed yield (653 kg ha -1 ) were obtained from sowing on 15 th November. Irrigation schedule also had significant effect on receme weight (g), number of seeds head -1, thousand grain weight (g), biological yield (kg ha -1 ) and seed yield (kg ha -1 ). Receme weight (2.76 g), number of seeds head -1 (40), thousand grain weight (3.55 g), biological yield (8530 kg ha -1 ) and seed yield (508 kg ha -1 ) were highest with 10 irrigations treatment, while two irrigations resulted minimum non productive branches plant -1 (1.48), receme weight (2.02 g ), thousand grain weight (2.99 g ), number of seeds head -1 (33) and seed yield (429 kg ha -1 ). It was concluded that planting of berseem either on 15 th November or 15 th December with ten irrigations were better in term seed yield production, and thus recommended for obtaining maximum yield in agro-climatic condition of Peshawar.
